The Qatari index added 0.7%, extending gains for a third consecutive day, helped by a 2.1% rise in petrochemical firm Industries Qatar and a 2.3% leap in Mesaieed Petrochemical.
The Abu Dhabi index retreated 0.3%, after three sessions of gains, as market heavyweight First Abu Dhabi Bank lost 0.8% and Emirates Telecommunications Group dropped 1.2%.
